Monroe is recovering from a concussion sustained in practice last week. Smith has been out since early this month with a groin injury. Cox injured his left hamstring in the preseason opener and has been sidelined since. And Rackley suffered a high ankle sprain late last month and has yet to return.

Cornerback Rashean Mathis, meanwhile, is expected to make his preseason debut against the Ravens. The Jaguars held Mathis out of the first two exhibition games as a precaution. He tore the anterior cruciate ligament in his left knee in November.
